Eight tips to improve the efficiency of LED power supply

LED Power Supplysfyh
1. The main current loop PCB should be as short as possible.   LAYPCB experience, and layout, this is nothing, the quick way is to look at the works of big factories.   2. Optimize the design of 300w LED transformer parameters to reduce eddy current loss caused by ringing.   This is more difficult. First, you must master the basic knowledge of electromagnetics and design a reasonable transformer. The most important thing is patience. Even if you think of improving the efficiency by 0.5%, you must try.   3. Reasonably select switching devices.   This is the balance between cost and performance. What kind of…

How much do you know about DALI dimming?

LED Power Supplysfyh
DALI dimming products are developed and designed based on the DALI protocol, DALI “digital lighting control international standard, the full name is: digital addressable interface standard, DALI protocol is an open asynchronous serial digital communication protocol. DALI protocol is dedicated to lighting control protocol, only used in lighting systems. The open standard of DALI protocol makes DALI dimming power supply very compatible. As long as the company that produces LED dimming power supplies joins the DALI Association, they have all DALI According to the agreement, power products that meet all DALI standards can be developed and produced.    The above…

What size led driver do I need?

LED Power Supplysfyh
In some cases, one of the biggiest factor to choose the best led driver is the size.When your LEDs are relative small and need the compact size of the led driver,  the 12v 6w led driver is small and suitable for your project. When your project are looking for the medium size, our 24vdc 80w led driver 190*48*34mm  would be your first demand of your thoughts. Also, we also had some big wats like 12v 200 watt 300watt led power supply, which could meet some of your big watts led strip lighting project. That would be helpful and possible for…

What is the influence of ripple in a LED driver?

LED Power Supplysfyh
The ripple processing will directly affects the working performance of the electrical products that the constant current or constant voltage LED driver carries. For different electronic products, the processing requirements for ripple are different. There is no standard for the range, but the smaller the processing, the better. For the consumption of LED lights, there will be some impact. If using poor quality power supply, this will accelerate the light decay and heat generation of the LED light, it is necessary to minimize and control the ripple. Otherwise, the LED light will fade too fast and will become less and…

What is drive power ?

LED Power Supplysfyh
For lighting, the development of LED has actually entered a new stage, with high requirements for the driving power of the LED light source: High efficiency and low heat generation, because the LED power supply is usually built-in with the LED lamp beads, the heat emitted by the power supply and the LED chip will be superimposed, when the heat generation and dissipation are balanced, the working temperature of the LED light source is finally determined together, and the LED lamp beads work The temperature determines the service life of the LED light source: The led driver power supply has…

Basic knowledge of LED dimming power supply

LED Power Supplysfyh
First, if you want to have a good use effect in the later stage, you need to pay more attention when purchasing, especially the operating environment of this type of equipment may be different, so it must have good anti-interference, environmental adaptability and corrosion resistance. Moisture resistance, etc. Second, no product can choose the most expensive is the best. You must first understand your own needs and choose a suitable LED dimming power supply based on daily operating standards, so that it can be used in the later process. Play a better effect. Third, under normal circumstances, it is necessary…

Does the LED dimming power supply have room for future development?

LED Power Supplysfyh
Speaking of LED dimming power supplies, many people will not find it unfamiliar. This is a kind of equipment that needs to be used in many places. With the continuous development of high technology, the scope of application of dimming power supplies is now becoming more and more extensive. So is the future development space of LED dimming power supplies broad? Which areas are to be developed? The stability of the LED dimming driver is very reliable, and it is also very recognized by many users now. Compared with the traditional dimming power supply, there will be no unstable effects such as…
